Although Palin has not said whether she will run, her appearance in Iowa -- especially now -- will undoubtedly fuel speculation that she is.

Palin's visit to Iowa came just one day after Michele Bachmann, R-Minnesota, launched her own presidential campaign there and coincided with President Barack Obama's visit to Bettendorf, Iowa.

Iowa holds the first contest in the presidential caucus and primary calendar. How "The Undefeated" is received there could be a barometer of Palin's appeal in the state.

The film, produced by conservative filmmaker Stephen Bannon, cost $1 million to produce. It takes a flattering look at Palin's record as governor of Alaska, including reform efforts. It also covers her entrance onto the national political stage as Sen. John McCain's running mate in the 2008 presidential election.

After watching the film, Palin described it as "awesome" and "all about America's values."

To a group of people who attended the premiere, she said the film tries to set the record straight and talks about issues ignored by the "lame-stream media."

Palin told that group: "You don't need a title. You don't need a political position."
